This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Nissan's plan to supply US Mitsubishi dealers with family sedan stalls

Mitsubishi has quietly had some big success recently. The Japanese brand sold 77,643 vehicles in the US for all of 2014, a 24.8 percent jump over 2013. While still relatively small overall (Ford sold 74,355 F-Series trucks just in December, for example), it shows definite growth for the sometimes forgotten automaker. Unfortunately, the latest news might not help the company's future expansion. The proposed partnership of Mitsubishi and the Renault-Nissan Alliance on at least one midsize sedan for the US market is off the table, according to Automotive News. The company informed sellers that the collaboration had fallen through during a National Automobile Dealers Association meeting. "I told them that the plan has stalled," said Don Swearingen, executive vice president of Mitsubishi Motors North America, to Automotive News. "And I said that's really all I can tell you at this time." Under the original partnership, Mitsubishi was supposed to get a D-segment sedan that would have been built at the Renault-Samsung factory in Busan, South Korea. The automakers were also negotiating for Mitsu to get a C-segment four-door as a global model and developing an electric kei car for Japan together, due in 2016. While the sedan is gone, Mitsubishi isn't completely bereft of improved products in the pipeline. The Mirage Sedan is being launched in the US, and the Outlander is supposed to get a redesign for the 2016 model year. According to Automotive News, the Outlander Sport and Lancer are also due for refreshes in 2016, and a new Mirage is on the way.

Nissan e-NV200 EV charges into Tokyo

Nissan has already shown its e-NV200 in Detroit and Frankfurt in conceptual form, now its home market is getting an up-close look at the production all-electric compact van at the Tokyo Motor Show. While it doesn't sound like the e-NV200 will be making its way to the US anytime soon, it will go on sale on sale in Europe in the middle of next year and in Japan by early 2015.
The electric NV200 will be built in Barcelona, Spain, and while that EV-minded city has committed to using the van for public transportation, Nissan's hometown of Yokohama, Japan will also put the zero-emission vehicle to work in its public services fleet. Nissan has yet to reveal the production specs for the e-NV200 - including range - we do know that it will share much of its drivetrain with smaller Nissan Leaf. Check out the press release posted below for more information about the e-NV200 and Nissan's EV efforts in Yokohama.
